Abstract
A system which utilizes a digital correlator to determine the time of arrival of a received pseudonoise sequence. At the same time, the incoming pseudonoise sequence is quantized to higher resolution and passed through a digital delay line with a total delay of slightly greater than the duration of the pseudonoise sequence itself. From the time of arrival measurement, a clock strobe timing is established to do active correlation on the delayed received sequence as it emerges from the delay line. The results of the active correlation are accumulated and/or added to obtain the amplitude of the received signal.
